Title: Pulse code modulating circuit
Inventor: SATO TETSUO
IPC: G10L19/00
Filed: 1985-02-04
Abstract: PURPOSE:To reduce granular noise and inclined overload noise effectively by compressing change of amplitude of pulse modulated analog input signals by a logarithmic compander. CONSTITUTION:Amplitude of analog input signals Ain is compressed by a loga rithmic companding circuit 11, and converted to analog signals f (Ain) and supplied to a pulse modulating circuit 1. Then, the difference DELTAn obtained from quantized value of the signals f (Ain) is transmitted to a demodulating circuit 2. In the demodulating circuit 2, analog signals f (Aout) logarithmic compressed from the difference DELTAn are obtained by operation reverse to the modulating circuit 1. Amplitude of the signals (f) (Aout) is expanded by an inverse logarith mic companding circuit 13, and demodulated output signals Aout of nearly the same amplitude with the input signals Ain are obtained. Thus, granular noise and inclined overload noise can be reduced effectively.

Title: Operation of blast furnace
Inventor: SATO TAKESHI
IPC: C21B5/00
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To prevent the abnormal dropping of charged materials of slipping, hanging, etc., obstructing the stable operation of a blast furnace by quantifying the developing conditions of the abnormal dropping of the charged materials under consideration of the variation of ore/coke ratio distribution in the radial direction of the furnace top caused by the charging material distribution and complicated powder pressure distribution developed in the furnace and executing the charging material distribution control as an operational factor in the individual blast furnace. SOLUTION: In order to execute the charging material distribution control, the powder pressure distribution in the vertical direction in the furnace is necessary to predict. For this purpose, arbitrary charging pattern and ore/coke ratio are inputted into a material model to obtain an ore layer thickness ratio distribution, and further, the powder pressure distribution is predicted by using a prescribed equation from this ore layer thickness ratio distribution. On the other hand, a furnace gas pressure loss is predicted by using a prescribed equation based on the distribution in the radius direction of the furnace of the ore layer thickness ratio, grain diameter and space ratio and the blasting condition.  Then, the ratio of the furnace gas pressure loss to the powder pressure in the vertical direction is calculated and the charging material distribution control is executed so that this ratio does not exceed 1.

Thereby, an  aqueous mixture is obtained. The mixture is packed in the container made of the  easily breakable material such as glass, ceramic, plastic, etc. When a fire breaks  out, the container is placed near a fire-extinguished object and is broken by the  thermal expansion pressure of the aqueous mixed fire-extinguishing agent. Thereby,  the agent is foamed and discharged to extinguish the fire.

Abstract: PURPOSE:To provide the subject derivatives useful as an intermediate for synthesis of isoprenoid type phospholipids capable of producing a membrane, excellent in biocompatibility and membrane flow properties with high barrier properties, and also excellent in dispersion stability and chemical stability and capable of forming an intermolecule association. CONSTITUTION:A natural diterpene, (7R,11R)-phytol of formula I is hydrogenated in the presence of platinum oxide catalyst, subsequently oxidized in the presence of ruthenium trichloride catalyst to obtain a carboxylic acid derivative. The resultant carboxylic acid derivative is then converted to its acid chloride using thionyl chloride and then made to react with 3-benzyl-sn-glycerol in the presence of diisopropylethylamine. Benzyl group is subsequently eliminated to obtain a glycerol-1,2-diester derivative represented by formula II. This derivative is then allowed to react with diphenylphosphorochloridate in the presence of diisopropylethylamine to obtain its triphosphate and the resultant triphosphate is subsequently reacted with hydrogen in the presence of platinum oxide, thus obtaining the objective glycerol derivative shown by formula III (R and R' are H or phosphoric acid-protecting group; (n) is 1-3).

Title: Pilot operation type pressure compensation type flow control valve
Inventor: DENISU REI BAABAA
IPC: F15B11/05
Filed: 1994-01-19
Abstract: PURPOSE: To provide a pilot-actuated and pressure-compensated control valve having simple structure, a low cost, and a load sense prior function. CONSTITUTION: In a pilot-actuated and pressure-compensated flow and direction control valve 11, a main valve spool 95 is positioned in accordance with a pressure difference between plot and reaction chambers 119 and 117. The flow of fluid entering from an inlet port 29 to the chamber 119 is controlled by a pilot valve 97, while the fluid passes through a fixed orifice 67 from the chamber 119 to flow into a pump load sensible port 61. When load L pressure is higher than inlet pressure, the spool 95 is actuated as an inlet check valve, to prevent a back flow. When the load pressure of another load circuit in a device, e.g. of a steering valve S is higher, the pressure in the chamber 117 is increased, consequently the spool 95 is closed by this pressure increase to reduce the flow from the port 29 to an operation port 47, thereby giving priority to the valve S.

Title: Magneto-optical recording and reproducing device

IPC: G11B11/10
Filed: 1987-01-28
Abstract: PURPOSE:To improve the detecting ability for a defect part of an magneto- optical recording medium by providing a summing amplifier which detects the sum signal of information signals from 1st and 2nd photodetectors and an amplitude detecting circuit which detects the output signal of the summing amplifier exceeding a preset reference comparative amplitude value. CONSTITUTION:A recording signal from a magneto-optical recording medium 6 is read with laser light and inputted to photodetectors 11 and 11, and they are converted into electric signals, which are inputted to a differential amplifier 12 and the summing amplifier 18. Signal components detected by the photodetectors 11 and 11' are opposite in phase to each other, so almost none of them appears at the output of the summing amplifier 18. When a defect part which causes variation in reflection factor is reproduced, on the other hand, the signals detected by the photodetectors 11 and 11' are in phase with each other, so they are amplified by the summing amplifier 18 and outputted. When this exceeds the reference comparative amplitude value, a high level signal is outputted by a comparator 19 and inputted as a defect detection signal to a defect correcting circuit to correct the defect noise of a playback video signal.

A compression function is selected so that the Zi is attenuated from the point of time exceeding the amplitude 17 and converged into an operating point 24 equal to the amplitude 17 at an amplitude 20 gradually. The compression rate is changed at each one sampling interval, and the compression is stopped after time tau from a time 26 to obtain Ri=Zi. Thus, the output Ri of the circuit 5 is within a maximum amplitude em, allowing to prevent the overload.
